Distribution network capability as a limiting factor of wind power plant connection

Abstract

Lack of sufficient distribution network capability is seen in this paper as a limiting factor of wind power plant (WPP) installation. The problem is viewed from time domain responses of the WPP to wind speed changes. Being disturbed by a variable wind speed, the WPP injects variable active and reactive power into the distribution network exposing nearby consumers to excessive voltage changes. The WPP connection is analyzed with respect to line thermal limits, bus voltage fluctuations and network power loss. Potential electrical energy production of a real WPP installation site is related to surrounding distribution network capability. Recognized discrepancy pointed out to a necessity of application of further countermeasures should this installation site be made viable for full utilization.Index Terms -distribution network capability, thermal loading, voltage fluctuation, power loss, wind power plant (WPP)
